On our way home, we took a detour out to Box Elder, Utah, which is where the Golden Spike was set. The Golden Spike National Monument is there and it includes two completely functional, faithful reproductions of the Central Pacific's "Jupiter" and the Union Pacific's "119" locomotives. They fire them up twice a day and run them up and down the track.

The 119 runs on coal and the Jupiter on wood, just like the originals!
